BYRCE animation - it is possible

Animations in BRYCE are far and few in between - whether it's due to lack of awareness, or too complicated, I don't know? But the 'ware is certainly capable of producing such - the latest (here, a link to YouTube). This was a 'fun project', and while I understand that most can/will eventually get to such a level, BYRCE came through, if you want it to.

There are several free video editors out there: you will be given options to FREE downloads, which usually involves a 30-day free offer, with price-upgrade there aftwerwards.

A non-plus situation: where they have your details, and asking you to upgrade in the end, investment in graphic editors (can start from $50 to $200 or thereabouts) is recommended, if you want to produce animations.

Again, if you've fully set-up the Bryce animation, you can render it straight-thru as such; as a final .avi, but if you want to manipulate it further, then you will have to go through Bryce again, or use the graphics 'wares to do so.
